GIS conducts annual system update


Gwinnett County is currently acquiring aerial photography and survey ground control to update its Geographical Information System (GIS). The County contracted Sanborn Map Company to acquire this data. Sanborn's team for this service will include WK Dickson & Co. Inc., a surveying firm based in Raleigh.

Surveyors will place temporary 10′ to 12′ black and white plastic targets in the shape of a “V,” “X,” or “T” within the public right-of-way and other public access lands in the county. All targets will be removed after completion of the aerial flight and quality control of the images by mid-April.  

Please be careful to not disturb these targets. If you have any questions regarding this process, please contact Barry Puckett, ITS Acting Director at 770.822.8031 or barry.puckett@gwinnettcounty.com or Sharon Stevenson, GIS Manager, at 770.822.8033, sharon.stevenson@gwinnettcounty.com.
